Abstract
The utility model relates to the technical field of machining tools, particularly to a saw blade. The saw blade comprises a saw blade body, sawteeth are sequentially arranged at one side edge of the saw blade body, tops of the sawteeth are processed by high-frequency quenching, the hardness of the tops of the sawteeth is HRC 59-62 degrees, and the hardness of the saw bar body is HRC 42-44 degrees. According to the saw blade, high-frequency quenching process is only performed on the tops of the sawteeth, so that the tops of the sawteeth are provided with high hardness, the cutting property and the service life are improved, the cutting efficiency is greatly improved, the cutting quality is good, the saw blade can cut various materials, monocrystalline silicon and frozen meat, the application range is wide; and quenching process is not needed for the saw blade, so that the hardness of the saw blade body is different from that of the sawteeth, the flexibility is added in manufacturing process, both the toughness and the high hardness of the saw bar are guaranteed, the process is convenient, and the cost is low.
Description
Technical field:
The utility model relates to the machining tool technical field, refers in particular to saw blade.
Background technology:
Saw blade is widely used in a plurality of industries such as machine-building, Wood Processing, metallurgy, chemical industry, military project.Saw blade divides frame saw blade and bands for band again, and frame saw blade is not only thin but also long, Yi Bian the symmetry of hump is shaped on the saw of several sawtooth, this saw is installed in and carries out sawing workpieces on the buck saw lathe; Bands for band is not only thin but also long, one side the band saw that is shaped on several sawtooth of hump symmetry is installed in and carries out sawing work on the band saw lathe.
Existing saw blade is made up of the sawtooth of saw blade body, and in order to realize the better processability ability, the saw blade body requires to have high toughness, and sawtooth requires to have higher hardness; Because receive the restriction of cost and toughness reguirements, saw blade is generally all processed by high-carbon steel, improves hardness through the saw blade integral quenching; The hardness of saw blade integral body is all the same like this, so the sawtooth hardness of existing this saw blade is limited, stock-removing efficiency is low; Influence cutting quality, service life is short, restricted application.
The utility model content:
The purpose of the utility model is exactly to provide a kind of sawtooth hardness high saw blade to the deficiency of prior art existence.
To achieve these goals; The technical scheme that the utility model adopts is: saw blade, and it includes the saw blade body, and a lateral edges of saw blade body is arranged with the sawtooth that crown is handled through high-frequency quenching continuously; The crown hardness of sawtooth is HRC 59～62 degree, and the hardness of saw blade body is HRC 42～44 degree.
The crown hardness of said sawtooth is preferably the HRC61 degree, and the hardness of saw blade body is preferably the HRC43 degree.
The hardness of said sawtooth is successively decreased to tooth root by crown.
Said sawtooth and the saw blade body structure that is formed in one.
Said sawtooth left and right sides interlaced arrangement.
The material of said saw blade body, sawtooth is spring steel or high carbon tool steel.
The utility model beneficial effect is: the utility model includes the saw blade body, and a lateral edges of saw blade body is arranged with the sawtooth that crown is handled through high-frequency quenching continuously, and the crown hardness of sawtooth is HRC 59～62 degree; The hardness of saw blade body is HRC 42～44 degree, and the utility model only carries out the high-frequency quenching processing at the crown of sawtooth, makes the crown of sawtooth have higher hardness; Promote cutting ability and service life, increase substantially stock-removing efficiency, cutting quality is good; Can cut various materials and monocrystalline silicon and frozen meat, applied widely, the saw blade body does not need Quenching Treatment simultaneously; Make that the hardness of saw blade body and sawtooth is inequality, in manufacture process, increase flexibility, not only guarantee the toughness of saw blade body but also guarantee that sawtooth has sufficiently high hardness; And easy to process, cost is low.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model sawtooth.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described; See that shown in Fig. 1～2, the utility model includes saw blade body 1, a lateral edges of saw blade body 1 is arranged with sawtooth 2 continuously; The tooth root 22 that sawtooth 2 includes crown 21, is connected with saw blade body 1; Crown 21 is handled through high-frequency quenching, and crown 21 hardness of sawtooth 2 are HRC 59～62 degree, and the hardness of saw blade body 1 is HRC 42～44 degree.In this embodiment, crown 21 hardness of sawtooth 2 are preferably the HRC61 degree, and the hardness of saw blade body 1 is preferably the HRC43 degree, and the hardness of sawtooth 2 is successively decreased to tooth root 22 by crown 21, and the hardness of tooth root 22 is identical with the hardness of saw blade body 1, guarantee the performance of sawtooth 2.
Sawtooth 2 left and right sides interlaced arrangement, each tooth top tilt each other to the left and right, make sawtooth 2 undulate on saw blade body 1 arrange, and can obtain like this to make saw blade do not clamped by the material of sawing than the big slightly saw kerf of saw body thickness.
Sawtooth 2 and saw blade body 1 structure that is formed in one, easy to process.The material of saw blade body 1, sawtooth 2 is spring steel or high carbon tool steel, has suitable hardness and toughness.
The utility model only carries out the high-frequency quenching processing at the crown 21 of sawtooth 2, makes the crown 21 of sawtooth 2 have higher hardness, promotes cutting ability and service life; Improve 5～10 times of stock-removing efficiencies, cutting quality is good, can cut various materials and monocrystalline silicon and frozen meat; Applied widely, saw blade body 1 does not need Quenching Treatment simultaneously, makes that the hardness of saw blade body 1 and sawtooth 2 is inequality; In manufacture process, increase flexibility; Not only guarantee the toughness of saw blade body 1 but also guarantee that sawtooth 2 has sufficiently high hardness, and easy to process, cost is low.
Certainly, the above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
